Project

Title: New rules for the Topology Framework in gvSIG Desktop.

Student: Mauro Carlevaro.

Mentors: Óscar Martínez, Mario Carrera Rodriguez, Alfred de Jager and Francisco Peñarrubia.

Repository: Link to GitHub repository.

Brief Description

A new topology toolbox. This tool will provide a group of integrity rules that will check the validation of the geometries relationship in the data. A new topology data model can be created for each project. This toolbox provide a new set of tools to navigate, find and fix validation errors different from each topology rule. Right now, there are just a few topology rules implemented with a limited actions. This project will analize, implement and optimize a new set of rules that will be incorporated to this framework. This tools can be created in Java or in Jython through the Scripting composer tool.

State of the Project Before GSoC.

Only a few topology rules have been implemented until now, the most of them are still pending to be developed.

The addition that the project bring to the software.

A new set of topology rules for vector datasets validation and fixing is implemented, which improve and expand the existing before.

Deliverables

A new set of topology rules for vector datasets validation/fixing, that will improve and expand the existing one:

  • Must be coincident with..
  • Must be covered by endpoint of.
  • Points must be covered by line.
  • Must be properly inside polygons (PointMustBeProperlyInsidePolygonRule)
  • Must be covered by boundary of.
  • Must not overlap (Must not overlap polygon).
  • Must not have gaps.
  • Contains point.
  • Contains one point.
  • Must not overlap with.
  • Must be covered by.

Timeline

Pre Coding Period

Pre-Bonding Period (March 25th - April 9th)

  • Set up working environment, choose tools to be used in the project and set up repository.
  • Familiarize more deeply with the community.
  • Review and learn as much as possible about Python, Jython and Java.
  • Test the topology plugin and study the code of some rules that are already made.

Community Bonding Period (May 6th - May 27th)

  • Familiarize more deeply with the code, with the mentors of the project and with the documentation.
  • Study the Topology Framework API.
  • Study the algorithm for a correct implementation according to the established rules.
  • Set up the development environment.
  • Interact with mentors, introduce myself to the community and actively get involved in the discussion.
  • Set up the wiki page to keep track of weekly progress.
  • Introduce myself and the project on OSGeo's SOC mailing list.
  • Improve in the creation of scripts
